INSULATED DRYING FORM Filed `April 24, 1929 Patented Jan. 3, 1933 UNITED STATES PATENT oir-FICE JULIUS O. V. STETTEN, l02E' PHILADELPHIA,,IENNSYLVANIAASSIGNOR TO PARA- `IMIO'U'IN'JJ TEXTILE MACHDTERY COMPANY, 0F KANKAKEE, ILLINOIS, A. CORPORA- TION F ILLINOIS INSULATED DRYING FORM Application led April 24,

This invention relates to drying forms and more particularly to drying forms for ladies hosiery.

l In a large percentage ot ladies hose manu- 5 factured today, `the major portion oi' the hose is made of very thin silk, that is the major portion 'of the leg and top of Ithe foot is chidon, while the bottom oi the toot, toe, heel and sometimes the top of the leg are reinforced by means of an additional thread, or threads, and in some cases the sill; thread isreplaced by a relativ-ely heavy cotton or lisle thread or threads, to form a relatively heavy fabric.

It will therefore be appreciated'that when hose of this character are placed on the usual heated form, the chiffon porton will be dried almost instantly While considerable time will be required to dry the heavier portions, and if the form is heated to the proper temperature for quickly drying the heavier portions of the hose, the chii'on portions will be instantly dried, and will then be subjected to the heat of the form during the drying oi the heavier portions of the hose, which will tend to weaken the chiffon portions.

The object of my invention is to provide a drying form on which articles and particun larly hose having different portions of diiferent weights can be dried and shaped in substantially the same period of time. This is vaccomplished by partially insulating those portions of the form which are engaged'- by ,x the lighter or chifon portions of the article or hose.

The precise nature of my invention will be best understood by reference to the accompanying drawing which will now be described, it being premised, however, that changes may be made in the details of construction, without departing from the spirit and scope otmy invention as defined in the accompanying claims.

In the drawing- Fig; l is a side elevation of one form of a hosiery drying form made in accordance with my invention; and

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1.

'Y The form shown in the drawing is made 1929. Serial No. 357,677.

up of two side plates 10, welded to each other at their meeting edges 11, 11, and are also welded to a base 12, adapted to be secured to a suitable support.

Extending longitudinally through the central portion of the form from the base to a point adj acent to the end of the toe portion of the form is a.l separator 13 for causing the steam to flow upwardly along one side thereof and downwardly ontlieother side. The base 12 is provided withthe usual openings indicated in dotted lines through which the heating medium flows as indicated by the arrows inFig.V 1.

The form shown in the drawing" is adapted ior drying hosiery having a portion of the leg` and the top of the foot of chiffon,- while the toe, heel, bottom of the footand the top oi the leg are formed of relatively heavy fabric.

vIn :a form for drying hosiery of this type, I partially insulate the port-ions of the'form shown in F ig. 1, between lines A-vA and B-B, sov as to reduce the temperature of the external surface of the form between said lines below that of the other external `surface portions of the form, whereby the temperature of the indicated portions of the form above and below the lines A-A and B--Bis sufficiently higher than that of the indicated intermediate portion of the form to dry the heavier portions of the hose in about the same time that the chiffon portionl is dried.

I vaccomplish the above in the form shown by placing a lining of asbestos paper 14 of the proper shape,inamely, the shape between lines A-A and B-B, on the inside of the sideplates 10, :and secure over such portions a thin sheet of copper or other material 15,- to protect and prevent the heating Huid from washing out the insulating material.

It will be understood that various materialsv other than asbestos paper may be used for insulating portions of the form, and that material having the proper insulating qualities be used in accordance with the differential in temperatures required for drying the different portions of the article to be dried.

In the forni shown the sheet copper 15 is cut slightly larger than the asbestos, and is secured to the inside of the form beyond the edges of the asbestos, or the lines A-A and B-B, or the lining may be spot welded at different points to the surface of the plates.

Instead of placing sheet metal against the inner surface of the asbestos, it may be coated with any suitable substance which will protect the surface against the action of the heating fluid. Y

I also desire it to be understood that other means than that shown in the drawing may be used for heating the forms.

he advantages of my invention result from the provision of a form for drying and shaping articles, in which certain external surface portions of the form are arranged to be heated to a higher temperature than other surface portions, whereby all portions of an article can be dried and shaped in substantially the same period of time even though some of the portions of the article to be dried are heavier, or contain more moisture to be evaporated than other portions of the article.

I claim l. A hollow drying form for shaping articles to be dried, arranged for passing a heating fluid therethrough, and insulating material on portions of the inside of the form, whereby said insulated portions will not be heated to as high a temperature as the portions on which no insulating material has been placed.

2. A hollow drying form for shaping articles to be dried, arranged for passing a heating fluid therethrough, insulating material on portions of the inside of the form, whereby said insulated portions will not be heated to as high a temperature as the portions on which no insulating material has been placed, and a protective coating on said insulating material.

3. A hollow drying form for shaping articles to be dried, arranged for passing a heating fluid therethrough, and an asbestos lining secured to portions of the inner walls of the form.

4. A hollow drying form for shaping articles to be dried, arranged for passing a heating fluid therethrough, an asbestos lining secured to portions of the inner walls of the form, and a protective covering on said asbestos.

5. A hollow drying form for shaping articles to be dried, arranged for passing a heating fluid therethrough, an asbestos lining secured to portions of the inner walls of the form, and a protecting sheathing of metal covering said asbestos secured to the inner walls of the form.

6. A hosiery drying structure comprising a hollow form adapted to receive the article superposed thereon in drying position, an inner shell conforming in shape substantially tothe shape of the form and substantially 4co'r-iXt-ensive with predetermined fabric portions of said article, said shell being spaced at a predetermined distance from the interior surface of said form, and an insulating medium between said shell and form.

7. A hosiery drying structure comprising an outer shell shaped to receive a hosiery article having fabric portions of dissimilar texture, and an inner shell within said outer shell having its extremities substantially in alignment with the lines of junction of the dissimilar portions of the fabric of said article when said article is superposed on said outer shell in drying position, and an insulating medium between said shells.

8. A hosiery drying structure comprising an outer shell shaped to receive the hosiery article having fabric portions of dissimilar texture, an inner shell attached to said outer shell having its extremities substantially in alignment with the lines of junction of the dissimilar portions of the fabric of said article, and an insulating medium ybetween said shells.

9. A hosiery drying structure comprising a hollow form adapted to externally receive in drying position thereon a hosiery article having fabric portions of different weights and to internally receive a heating medium, said form having wall portions characterized by different thermal conductivities, the wall portions of higher conductivity being contiguous to the heavier fabric portions of the hosiery article.

l0. A hosiery drying structure comprising a hollow form adapted to externally receive in drying position thereon a hosiery article having fabric portions of different weights and to internally receive a heating medium, said form having wall portions characterized by different thermal conductivities, the wall portions of higher conductivity being contiguous to the heavier fabric portions of the hosiery article and the respective conductivities being adjusted to dry all portions of the article in substantially the same time.

ll. A hosiery drying structure comprising a hollow form adapted to externally receive in drying position thereon a stocking having a fabric leg portion of a given weight and a fabric foot portion of a relatively heavier weight, and to internally receive a heating medium, said form having wall portions characterized by different thermal conductivities, the wall portions of higher conductivity being contiguous to the foot portion and the remaining portions having a lower conductivity being contiguous to the leg portion.

In testimony whereof I affix my signature.
